According to the latest data from the International Energy Agency (World Energy Outlook 2019, Stated Policies Scenario), global energy demand will increase 1 per cent a year to 2040, due mainly to rising standards of living and population growth in the developing world. Use of renewables will increase significantly over this time period. More oil and more natural gas will be also be needed to ensure energy security. So as we move towards a lower-carbon future, the question is not which energy source, but how can we innovate to make the energy we have more sustainable?
